作者将28例长势良好、适于胎龄的VLBW婴儿随机分为两组,用非蛋白质强化的(14例)或人乳蛋白质强化的人奶(14例)喂养。分别选用下列四种方案之一,即(1)人奶(人乳库的成熟乳,或更好是婴儿母亲自己的奶),(2)人仍十人奶脂肪(1g/dl),(3)人奶+人奶蛋白质(1g/dl),(4)人奶+人奶脂肪(1g/dl)+人奶蛋白质(1g/dl)。各种奶均不经过巴斯德消毒处理。两组婴儿的出生体重(900～1500g)和胎龄(26～32周)相同。从平均日龄为19天(此时婴儿已能耐受全部奶量)开始,持续观察到平均日龄为28天。非蛋白 The authors randomized 28 healthy, gestational age VLBW infants to either a non-protein-fortified (14) or a human milk-fortified (14) human milk. One of the following four options is used: (1) human milk (mature milk from human breast milk, or better milk from infant mother), (2) human milk fat (1 g / dl), 3) human milk + human milk protein (1g / dl), (4) human milk + human milk fat (1g / dl) + human milk protein (1g / dl). All kinds of milk are not pasteurized. The birth weights (900-1500 g) and gestational age (26-32 weeks) for both groups of infants were similar. Starting from an average day of age of 19 days, at which point the baby has been able to tolerate the full amount of milk, the average age of 28 days was continuously observed. Non-protein
